Curious, I am the same way. I was really struggling with the idea
of Math when I decided to get my teaching credential - how can I teach someone else when I don't feel confident in it myself(?)
Then I met a very amazing Mathematics professor, and the light bulb turned on. I so wish I had this woman as a Math teacher somewhere in my formative years, it would have made a sea change in my attitude and understanding of the subject.
When I went into my first student teaching assignment, we gradually assumed control over subjects taught in the classroom. Guess which one my Master Teacher wanted me to take over first??? smileys/surprise.gif

If you want to share this with others, here's the breakdown (text written for Crystal Ball game)
To play this game (and others like it), you are requested to pick any 2-digit number, add the two digits together and subtract them from your original selection. For example, if you pick the number 89, you would add 8+9 = 17, then you subtract 17 from 89, which is equal to 72.
You are then told to look at the symbol next to "72" and think about it. When the game advances, they "show" you that exact image.
Here's how it works:
EVERY double-digit number that you add together AND then subtract from your number will end up being a FACTOR OF 9. A factor of 9 means any number that can be wholely divided by 9 with no remainder.
Those numbers are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90.
Go on, try it...I'll wait.
See...
How they rig the game? They put the exact same symbol at every one of those 9-Factor numbers, plus a few extra red herrings so the pattern isn't as obvious.
To play, you pick a number and do the math. (I guarantee you'll end up with one of those ten listed above.) After memorizing the symbol, you press the button and viola! It matches!
It matches because NO MATTER what number you originally picked--they have it covered by the factors of nine. They knew ahead of time what symbol to display because it's whatever symbol is currently at the 9-factor locations.
Then if you "play again" they simply shuffle the symbols around, but the nine-factors will always match, no matter what symbol is now selected for the 9-Factor numbers. And they'll display the new symbol in the crystal ball.
Here's how you can check: do everything they ask, but before you click on the crystal ball, look at each of the factors of nine (9, 18, 27, 36, 45, 54, 63, 72, 81, 90). I'll bet anything they match the one you came up with when you did the math. Then, when you press the crystal ball, it's already there. You're Psychic! Get yourself a 1-900-IKNOWALL phoneline and make yourself some money!
This is also why they make you pick a two digit number. It won't work with 0 through nine, but you don't really notice that when looking at the chart with 100 symbols.
It's a little sad once you know the solution, but there it is.

Yes, a good teacher makes such a difference. I went to a very small, rural highschool with less
than 20 in my graduating class. The coach usually got stuck with teaching math. And the coach was generally straight out of college with no interest in teaching math.
It was kind of funny, I was so bad at math, then when I got to college, I saw a course called Intro to Math and in my naivety, I thought, wow, this will explain it all to me and I signed up. It took two classes for the professor and I to both realize I was in waaaay over my head and I dropped it. And we won't talk about Intro to Spanish when you've never heard it spoken, let alone had a class in it. That was also a complete disaster. I should say this was many years ago.
